ABSTRACT:
A microcomputer includes a processor and an emulator interface circuit that provides processor state information to an external emulator. The emulator interface circuit operates at a clock speed that is lower than the clock speed of the processor and provides the state information at predetermined intervals, such as after a predetermined number of processor clock pulses. The state information may also be provided after a specified number of instruction fetches have occurred.
